Specification of Letters Patent.

Application :filed February 25, 1918. Serial No. 220,087.

To all whom t may concern:

Be it known that I, WALTER W. WARING, a citizen of the United States, residing at Sterling, in the county of Rice andState of Kansas, have invented certain new and useful Improvements in Pocket Index-Files, of which.l the following is a specification.

` This invention relates to pocket lfiles of' the accordion type bearing identification or index letters on the back walls'of the respective pockets, and my object is to produce a file of this character of such construction that'thc opening or spreading of a pocketor pockets so affects the back wall or walls thereof as to-more prominently display the identifying letter or letters thereof and thus ,facilitate the filing of letters or the like in the file or reference to the contents thereof. AY further object is to vproduce a file of this character which when opened, tends to remain in that condition and in an upright position, and thereby i makes for rapidity and accuracy of filing. v

With these generalV objects in view, the invention consists in certain novel and useful" features of construction and combinations of parts as Vhereinafter described and claimed; and in order that it may befully understood, rreference is to be had to the accompanying drawing, in which Figure'l, is a'fragmentary side vview of a pocket index le embodying the invention.

Fig 2, is a top plan view of the same.

Fig. 3, is a vertical section taken through one end/of a pocket, on the line III- III of Fig. 2. Y Y

Fig. 4, is a simila view taken through the side of the iile between adjacent pockets, on the line IV-IV of Fig. 2.

Fig. 5, is a perspective View of the upper part of the le.

Fig. 6, is a 'similar view of the sides of the file. f

In the said drawing, 1 indicates a strip of heavy paper or the like, folded accordion like, to form a plurality of V shaped pockets 2, of which 3 indicates the back walls and 4, the front walls, the wallsy 3, being horizontally creased to provide bending lines 5 near and parallel with their upper edges and equipped above said bending lines with index characters or the like, such as the letof a part of one 'ters of the alphabet, not shown, because common this class of files, each character 1 and ywhen the pockets are nearly closed and others identifying a particular pocket. The series of pockets are of integral formation though it is obvious they may be composed of strips of material bound together to constitute a unitinstead of being formed from a single folded strip as shown for convenience clearness of illustration.

The sides G of the file are likewise lmore clearly and conveniently shown as formed from single strips of material folded accordion like to form alternately arranged V shaped folds 7, and inverted Veshaped folds 8, the latter being truncated at their upperends, the junction lines of said folds 'coinciding with and being secured to the ends of the walls 3 and 4- of the pockets so Vthatvopening and closing movement of the atter shall effect lateral expansion or contraction of the end folds 7 and S, it being noted in this connection thatY the upper edges of the sides occupy a plane near and preferably slightly below that of the bending lines 5, to avoid interfering with folding and unfolding action of the back walls on said lines as the pockets are respectively Vopened or closed, the folding action on said lines causing the character-bearing portions of the pockets to face upwardly to agreater extent than the parts of said walls below said lines, and thus bring the said characters to positions where they can be seen to 'better advantage.

The central fold lines 9, of folds 7 which constitute the sides of the pockets, incline downwardly and outwardly to and intersect with the bottom of the filewhere the junction lines of the folds 7 and 8 meet or merge, (see Fig. 6) the inclinationbeing greatest fully collapsed or closed and very slight when the pockets are fully opened, this being noted by reference to Figs. 1 and 2, which show several pockets about fully opened.

rlhe central fold lines 10 of the folds 8, which constitute the sides of the le between the pockets, incline downwardly and inwardly or reversely to fold lines 9, and both sets of fold lines 9 and 10 stand in perpendicular planes as clearly shown in Fig. l.

The degree to which the pockets open depends on the depth of folds 7, and the degree to which the index-bearing portions of the back walls of the pockets fold or turn upward depends on the depth of folds `8, and

the leverage action thereof applied on the Walls ofthe pocketsA at or belowl the bending lines 5.

The general tendency 0f files of this class is to close, thus concealing the index and making it necessary tov open the l Dl'- liminary to identifying the desired pocket.

The tendency of this file, that the creases due to the fact 9fand`l lOof the pockets are substantially vertical when thefile is open,

is to stay open and hence maintain the file inaniipright position and provide for m'aXimum visibility` of the index at all timesiand therefore. makefor rapid'. and accurate ling.

From the above` description, itwillbe apparenti. that l .have produced a pocket index f le embodying the features-of advantage set forth as desirablein the statement ofV the object of the invention, and wliilel have illustratedthe preferred. construction, it is apparent-2v that the file'is susceptible 'of m'odilication in minor particulars wit-hout dethe. front andA back walls whereof. diverge parting: from the principle ofeonstruction involved. i' j I: cla-iin: Y
